[www.chinagoodwood.com] noise pollution is also our daily life, a very common one of a kind of pollution, it has seriously affected the quality of our daily life.How to choose and buy some more effective sound insulation broken bridge aluminum alloy doors and Windows, the rich hin doors and Windows to introduce soundproof Windows one by one to you how to choose and buy, let you have a quiet living environment.Poly Shutter The selection of window frame developers generally choose is aluminium alloy, but some are selected aluminium alloy is single cavity walls are thin, sounds easy to penetrate, and broken bridge aluminum cavity, wall thickness thicker than ordinary aluminium alloy window, the voice is not easy to penetrate.The choice of article 2 of sound insulation developers choose mostly article aluminum alloy frame with rubber insulation or wool insulation, but wool insulation used long would be easy to hair removal, the capacity of the rubber is used long after the storm or harden aging, so the article sound insulation to prevent aging and keep toughness.Currently on the market have a kind of import of sound insulation, leather material package is outside, inside chosen is sound-absorbing cotton, as it is not easy to aging and toughness, good to ensure the sealing of the window frame leaky point.3 most important The choice of sound insulation glass Now in the market are mainly hollow glass, laminated glass, vacuum glass.Vacuum glass using the principle of vacuum cannot spread of sound, after installation, can the noise reduction 30-40 decibels.Floors high,China Poly Shutter such as near 20 layers above and there is no train large trailer can consider to choose hollow glass or laminated glass;Floor low and close to the road or near viaduct and low frequency noise, then consider using vacuum glass, so as to thoroughly solve the problem of noise.4 the principle of heat insulation window wall construction projects are generally adopted heat preservation processing, due to the influence of the indoor and outdoor temperature and humidity, often in the winter and summer temperature difference was in the window and easily produce the phenomenon such as condensation or condensation in areas such as the ring beam, the energy loss.At this time for these areas have special processing methods, broken bridge the resulting window, because the form of glass can be for two layer, there is air layer can be a very good energy saving effect,Poly Shutter Wholesale and the form of direct contact with wall profiles into weak positions.5 after the installation of frames of the seal do sound insulation window of aluminium alloy door window frame around how much will leave a small gap, so after installation must use glass glue to stick around the window.The seal around the looks be like simple, but still want to find a professional teacher to do to do perfectly.
